  The purpose of this research is to identify the determinants of loyalty in online games. This study developed a research model to analyze the factors explaining the loyalty level from gamers, employing social identification, flow, and positive anticipated emotion as major research variables, and collected 1308 survey responses from gamers. Within the context of arguing that the exploration of age range issues with respect to online games is important, this research also examines the age differences in path coefficients. To this end, the structural model was tested with the data from entire data sample (i.e., the age of 10s, 20s, and 30s pooled together) and each of the subsamples (i.e., teens taken separately, twenties taken separately, and thirties taken separately). Properties of the causal paths, including standardized path coefficients, the significance of difference, in the hypothesized model, are also presented, so that we can investigate the relative influences of different dominants, demonstrating how teens, twenties, and thirties differ in their decision-making processes regarding the flow, social identification and loyalty from online games.

엄명용(Myoung-Yong Um),김태웅(Tae-Ung Kim) 한국콘텐츠학회 2010 한국콘텐츠학회논문지 Vol.10 No.8

본 논문의 목적은 디지털 콘텐츠에 대한 사용자의 몰입경험(flow experience)을 탐색하는 것이다. 구체적으로, 본 논문은 디지털 콘텐츠에 대한 몰입경험을 온라인게임 사례(case)에 적용하여 도전감과 숙련도가 사용자의 몰입경험에 어떠한 영향을 주는가를 실증적으로 분석하였다. 연구결과 도전감과 숙련도의 수준(낮음, 보통, 높음)에 따라 디지털 콘텐츠(온라인게임) 사용자의 몰입경험은 유의한 차이를 보였다. 또한, 몰입경험에 대한 도전감과 숙련도 사이의 상호작용(interaction effect)은 존재하지 않는 것으로 나타났다. 본 논문의 결과는 향후 디지털 콘텐츠를 개발하고 디자인하는 IT기업에게 유용한 시사점을 제공하리라 본다. The purpose of this paper is to examine a user's flow experience of digital contents. In the paper, the flow experience of digital contents was applied to the case of online games and it was experimentally investigated whether challenge and skill affect the user's flow experience. The results of the paper indicate that there are differences in the flow experience according to the level (low, medium, high) of challenge and skill in the context of online games. Furthermore, there is no interaction effect between challenge and skill affecting flow experience. The findings provide useful implications for IT firms that will plan to develop and design digital contents.

공급망 통합 및 성과의 영향요인과 조절변수 탐색

엄명용(Myoung-Yong Um) 한국콘텐츠학회 2018 한국콘텐츠학회논문지 Vol.18 No.4

최근 들어 많은 기업들이 개별 기업의 경쟁력보다는 어떻게 공급망의 경쟁력을 높일 수 있는가에 더 많은 관심을 보이고 있다. 본 연구의 목적은 공급망상에서 기업 간 신뢰, 통합, 그리고 성과 사이의 관계를 고찰하고, 기업규모와 흡수역랑이 이러한 관계들을 어떻게 조절할 수 있는가를 실증하는 것이다. 두 요인들 사이의 인과관계와 조절효과로 제시된 가설들을 검정하기 위하여 111개의 설문 데이터가 본 연구에서 사용되었다. 연구결과 공급망 성과는 기업 간 신뢰뿐만 아니라, 공급망 통합에 의해서도 긍정적인 영향을 받는 것으로 나타났다. 또한 신뢰는 공급망 통합에 유의한 영향을 미치는 것으로 나타났다. 기업규모에 대한 조절효과결과, 신뢰와 공급망 성과 사이의 관계는 소규모 집단이 대규모 집단보다 상대적으로 더 강한 인과관계를 가지는 것으로 나타났다. 그러나 공급망 통합과 공급망 성과 사이의 관계에서는 대규모 집단이 더 강한 인과관계를 보여주었다. 흡수역량에 대한 조절효과는 신뢰와 공급망 통합의 관계에서 그리고 공급망 통합과 공급망 성과와의 관계에서 고흡수 집단이 저흡수 집단에 비하여 더 강한 인과관계를 보였다. 본 연구의 결과는 서로 다른 기업규모와 흡수역량을 가진 공급망 참여 기업들에게 의미 있는 함의를 제공할 것이다. Recently, many firms have been more interested in how the competitiveness of the supply chain can be enhanced, rather than that of the respective company. The purpose of this study is not only to investigate the relationships among the trust between companies, the supply chain integration, and the supply chain performance, but also to demonstrate how the firm size and the absorptive capacity can moderate these relationships. To conduct the hypothesis test including the causal relations between two factors and the moderating effects, 111 data were collected through a survey. As a result, the supply chain performance was positively affected by the supply chain integration as well as the trust between the companies. In addition, the trust had a significant effect on the supply chain performance. The result of the moderating effect of firm size indicates that, compared with a larger group, a smaller group has a stronger relationship between the trust and the supply chain performance, while the relationship between the supply chain integration and the supply chain performance is much stronger in the large group than the small group. As for the moderating effect of absorptive capacity, a higher absorptive group has stronger relationships between the trust and supply chain integration, and supply chain integration and supply chain performance than a lower absorptive group. The findings would provide significant implications for supply chain partners with different sizes and absorptive capacity.

본 연구는 모바일 메신저 애플리케이션과 사용자 사이에 인지된 상호작용성이 어떻게 즐거운 감정과 지속적 사용의도를 유발시키는가를 검증하기 위하여 수행되었다. 본 연구는 메신저 애플리케이션에 대한 사용자의 인지된 상호작용성이 제어, 공유, 응답 요인에 의하여 형성된다고 보았다. 인지된 상호작용성, 즐거움, 사용의도 사이의 관계는 PAD 감정모형, 합리적 행동이론, 그리고 계획된 행동이론을 이용하여 연구가설로 설정되었다. 연구모형을 검증하기 위하여 한국과 중국에서 총 481개의 설문 데이터가 수집되었고, 구조방정식을 이용하여 가설을 검증하였다. 연구결과, 인지된 상호작용성인 공유와 응답 요인은 즐거움에 긍정적 영향을 미칠 뿐만 아니라, 사용의도에도 유의한 영향력을 가지는 것으로 도출되었다. 그러나 제어는 사용의도에는 긍정적 영향을 주지만, 즐거움에는 유의한 영향력을 가지지 않는 것으로 도출되었다. 그리고 즐거움과 사용의도 사이에는 긍정적 인과관계가 존재하였다. 본 연구는 부가적으로 한국과 중국 사용자들 사이의 차이점을 탐색하기 위하여 다중집단 차이분석을 실시하였다. 연구 결과를 바탕으로 모바일 메신저 서비스를 제공하는 기업들에게 인지된 상호작용성이 가지는 인과적 영향력과 한국과 중국 사이에 존재하는 경로계수 차이에 대한 시사점을 논의하였다. This study aims to investigate how perceived interactivity between the mobile messenger application and its user gives rise to user’s enjoyment and continuous usage intention. Perceived interactivity was assumed to be formed by the combination of control, share, and responsiveness in light of the previous studies. The relations between perceived interactivity, enjoyment, and usage intention are hypothesized on the basis of the pleasure-arousal-dominance emotional state model, the theory of reasoned action, and the theory of planned behavior. Survey data were collected from 481 mobile messenger users in Korea and China. In order to test hypotheses, structural equation modeling analyses were conducted. As a result, perceived interactivity concerning connectedness and responsiveness not only positively affected enjoyment, but also had a significant effect on usage intention. However, while control positively influenced usage intention, it was not significantly related to enjoyment. In addition, there was a positive relation between enjoyment and usage intention. Incidentally, multi-group analysis was conducted to explore the differences between Korean and Chinese users. The findings would provide managerial implications for mobile messenger corporations on causal effects of perceived interactivity and the differences of the path coefficients between in Korea and China.

확장된 기술수용모형을 이용한 온라인 게임 성공요인 분석 - 일본 게이머를 중심으로

엄명용(Um Myoung Yong),조성한(Jo Sung han),김태웅(Kim Tae Ung) 한국무역상무학회 2006 貿易商務硏究 Vol.29 No.-

Online game business has emerged as the most lucrative entertainment industry, with over 10 million players in South Korea and over 30 million in Japan in 2005. The popularity of online games can be attributed to the availability of broadband network, pushing online games into the mainstream entertainment culture. The age distribution of online game players is expanding and a variety of new games are under development to target certain age groups. While the interactive entertainment market continues to expand, with many new online game publishers entering the Japan, relatively little is known about which factors influence online game players' behavioral intentions to play continuously in this area. This study investigates major factors which influence the acceptance of online game services based on the theoretical backgrounds of the technology acceptance model(TAM) and the flow theory. This paper extended the Davis' TAM model by including the flow concept as another major factor toward the intention to play online game. Based on data collected from online questionnaire survey, we show that the proposed model provides an adequate fit to the data, and that the flow experience is another important factor influencing the intention to play online game, as well as the perceived ease of use.

문화콘텐츠 확산에 관한 비교 문화적 연구

Online game business has emerged as one of the most lucrative entertainment industry. The popularity of online games can be attributed to reliable broadband internet services and high quality contents. The age distribution of online game players is expanding and a variety of new games are under development to target certain age groups. While the online games markets continue to expand, relatively little theory has been developed about which factors influence flow, social relationship, and word-of-mouth in online games situations. This research focuses on three research questions on online game customers` behavior in Korea and the UK. The first research question is to examine the effects of the flow and the social relationship on the word-of-mouth in the two countries. The second question is concerned with reconfirming the findings from previous studies that the challenge and the skill have been found to affect the flow. And the final, third question is to explore the differences between Korean and British online game customers in terms of the relationships of these key factors (i.e., word-of-mouth, social relationship, flow, challenge, and skill). To test the above research questions, the author collect data from Korean (N=183) and British online game customers (N=192). The proposed structural model was tested using the PLS (Partial Least Square) statistical program. The results indicate that the flow and the social relationship have positive influences on the word-of-mouth, and the flow has significant influence on the social relationship not only in Korea but also in the UK. It was also found that both the challenge and the skill have effects on the flow in two countries. In addition, some differences between Korean and British online game customers were found. Korean online game customers were found to respond more sensitively than British customers concerning the effect of the social relationship on the word-of-mouth. However, British online game customers were found to have strong causal relationships than Korean customers concerning the challenge→flow, skill→flow, flow→social relationship, and flow→word-of-mouth. This empirical research provides managerial implications for the online game enterprises on how to strategically use the flow, challenge, skill, and social relationship to enhance the word-of-mouth in Korea and the UK. Nevertheless, some limitations of this study should be noted. First, the responses to this study were voluntary and thus inevitably subject to self-selection biases. Conceivably, customers who feel comfortable with playing online games may have been more likely to respond to the survey. Second, the multi-group (Korea and the UK) comparison can explore systematically the similarities and differences between the two countries, but this method in itself could not supply substantial information on the causes that induce those similarities and differences. Therefore, to some extent, the applications of this research require cautions. However, because online game industry is still at an early stage, the findings are expected to provide informative policy implications for the online game enterprises which have been considering the release of new online games in Korea and the UK.
